Abstract:
Enteric gram-negative bacteria-associated peritoneal dialysis (PD) peritonitis is common. These organisms are such as Escherichia coli, Klebsiella and Enterobacter species. Pantoea dispersa belongs to the order Enterobacterales, it has known benefits and a role in agricultural and environmental biotechnology. Pantoea dispersa, although still relatively rare, is being increasingly recognised to cause human infections. We are reporting a case of PD peritonitis caused by Pantoea dispersa in a kidney failure patient on continuous ambulatory peritoneal dialysis (CAPD). His peritonitis was treated well with intraperitoneal antibiotics and the patient can resume his CAPD therapy. The increasing reports of Pantoea dispersa-related human infections warrant concerns, both in immunocompromised and immunocompetent patients.
Insights
Peritonitis from enteric gram-negative bacteria is common in peritoneal dialysis (PD) patients. A rare case of Pantoea dispersa peritonitis was successfully treated with antibiotics, allowing the patient to resume continuous ambulatory peritoneal dialysis (CAPD).
Area of Science:
- Nephrology
- Infectious Diseases
- Microbiology
Background:
- Enteric gram-negative bacteria frequently cause peritonitis in patients undergoing peritoneal dialysis (PD).
- Pantoea dispersa, an emerging pathogen, is increasingly implicated in human infections, despite its known roles in biotechnology.
Observation:
- A case of continuous ambulatory peritoneal dialysis (CAPD)-associated peritonitis caused by Pantoea dispersa is presented.
- The patient had end-stage renal disease requiring CAPD therapy.
Findings:
- The peritonitis was successfully treated with intraperitoneal antibiotics.
- The patient was able to resume his CAPD therapy following treatment.
Implications:
- The increasing recognition of Pantoea dispersa as a human pathogen necessitates awareness among healthcare providers.
- This case highlights the importance of considering less common organisms in PD peritonitis management.
- Further research into Pantoea dispersa infections in both immunocompromised and immunocompetent individuals is warranted.
